From 98de31e836a04ccc8f5f9acd90b9ba0803a24ab5 Mon Sep 17 00:00:00 2001 From: Stavros Aronis Date: Fri, 18 Jun 2010 03:44:25 +0300 Subject: Test suites for Dialyzer This is a transcription of most of the cvs.srv.it.uu.se:/hipe repository dialyzer_tests into test suites that use the test server framework. See README for information on how to use the included scripts for modifications and updates. When testing Dialyzer it's important that several OTP modules are included in the plt. The suites takes care of that too. --- .../src/pubsub/pubsub_api.erl | 99 ++++++++++++++++++++++ .../src/pubsub/pubsub_publish.erl | 50 +++++++++++ 2 files changed, 149 insertions(+) create mode 100644 lib/dialyzer/test/small_tests_SUITE_data/src/pubsub/pubsub_api.erl create mode 100644 lib/dialyzer/test/small_tests_SUITE_data/src/pubsub/pubsub_publish.erl (limited to 'lib/dialyzer/test/small_tests_SUITE_data/src/pubsub') diff --git a/lib/dialyzer/test/small_tests_SUITE_data/src/pubsub/pubsub_api.erl b/lib/dialyzer/test/small_tests_SUITE_data/src/pubsub/pubsub_api.erl new file mode 100644 index 0000000000..c30233b8f5 --- /dev/null +++ b/lib/dialyzer/test/small_tests_SUITE_data/src/pubsub/pubsub_api.erl @@ -0,0 +1,99 @@ +% Copyright 2007-2008 Konrad-Zuse-Zentrum für Informationstechnik Berlin +% +% Licensed under the Apache License, Version 2.0 (the "License"); +% you may not use this file except in compliance with the License. +% You may obtain a copy of the License at +% +% http://www.apache.org/licenses/LICENSE-2.0 +% +% Unless required by applicable law or agreed to in writing, software +% distributed under the License is distributed on an "AS IS" BASIS, +% WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +% See the License for the specific language governing permissions and +% limitations under the License. +%%%------------------------------------------------------------------- +%%% File : pubsub_api.erl +%%% Author : Thorsten Schuett +%%% Description : Publish API function +%%% +%%% Created : 17 Sep 2007 by Thorsten Schuett +%%%------------------------------------------------------------------- +%% @author Thorsten Schuett +%% @copyright 2007-2008 Konrad-Zuse-Zentrum für Informationstechnik Berlin +%% @version $Id $ +-module(pubsub_dir.pubsub_api). + +-author('schuett@zib.de'). +-vsn('$Id: pubsub_api.erl,v 1.1 2009/11/06 12:39:55 maria Exp $ '). + +-export([publish/2, subscribe/2, unsubscribe/2, get_subscribers/1]). + +-import(transstore.transaction_api). +-import(io). +-import(lists). + +%%==================================================================== +%% public functions +%%==================================================================== + +%% @doc publishs an event under a given topic. +%% called e.g. from the java-interface +%% @spec publish(string(), string()) -> ok +publish(Topic, Content) -> + Subscribers = get_subscribers(Topic), + io:format("calling subscribers ~p~n", [Subscribers]), + lists:foreach(fun (Subscriber) -> + io:format("calling ~p~n", [Subscriber]), + pubsub_publish:publish(Subscriber, Topic, Content) + end, + Subscribers), + ok. + +%% @doc subscribes a url for a topic. +%% called e.g. from the java-interface +%% @spec subscribe(string(), string()) -> ok | {fail, term()} +subscribe(Topic, URL) -> + TFun = fun(TransLog) -> + {{Success, _ValueOrReason} = Result, TransLog1} = transaction_api:read(Topic, TransLog), + {Result2, TransLog2} = if + Success == fail -> + transaction_api:write(Topic, [URL], TransLog); %obacht: muss TransLog sein!
